  • 3 eggs
  • 1 cup of white sugar
  • 1 1/2 cups of brown sugar packed
  • 2 tsp baking soda
  • 2 tsp vanilla
  • 1 tsp corn syrup
  • 1/2 cup butter (one cube) room temp
  • 1 1/2 cups natural chunky peanut butter
  • 4 1/2 cups old fashioned oats
  • 1 cup of chocolate chips
  • 1 cup of M&M's
  1. Preheat oven to 350 degrees.
  2. In an electric mixing bowl, beat eggs until slightly foamy, about 1 min
  3. Add in white and brown sugar, beat on high speed until eggs and sugar are light and airy, about 3-5 minutes.
  4. Turn mixer off and add in baking soda, vanilla, and corn syrup. Mix on low speed for 1-2 minutes.
  5. Add in 1/2 cup of butter, mix on medium speed until well incorporated.
  6. Next, add in peanut butter and mix on medium speed for 1-2 minutes.
  7. With mixer on low speed, slowly add in old fashioned oats, about half cup to one cup at a time.
  8. Next add chocolate chips.
  9. Finally, add in M&M's and mix until just incorporated.
  10. Scoop cookie dough with a large spoon (generous tablespoon) onto cookie sheet. (I do 9 cookies per baking sheet). Slightly flatten the cookies before baking.
  11. Bake for 8-9 minutes, turning halfway through. Bake for 10 minutes if you like more of a crisp cookie. Let cookies cool on baking sheet for about 5 minutes and then move to wire rack (or newspaper, my mom always put her cookies on newspaper, so that's what I use, or I cut open a brown paper bag)
